Why is the median used instead of the mean?
There are several ways to calculate the centralvalue. The two most common are the mean and the median. The mean is calculated by adding all of the values and dividing the total by the number of values. For example, the average of 1, 2, 3, 4, 5 is 1 + 2 + 3 + 4 + 5 / 5 (there are 5 values) which equals 3. There are several disadvantages in using the mean as the central value.
